can someone please docode these #'s for me?
 

these are on the intake, its a weiland, old i think, square port-WCPSQ

these are the head #'s-GM14T, GM13T, 6272292

block #'s (454 but i would like to know year)8573, 3999289, conv1, GM10T

i am mainly interested in finding out if the heads are any good, thanks guys

heads:
6272292....70-78...oval...OPEN...402, 454

block:
3999289....454.......72-79...2 or 4 bolt, some "CE" replacement blocks had four bolt main caps


easiest way i know to find out about the weiand intake, is go to
http://www.holley.com
and find the weiand section and look up the numbers.

thanks man, i'm confused aobu thead #'s, when people ask me what # heads i ahve(ex. 149, i think) what do i tell them? how do i find that #?

last three numbers in the long number i decoded it with, you have 292 heads. my heads are:

3973487....71-72...350..........used on 71-72 350 LT1, 75cc chamber

so they are 487s.

thanks man, you never know til you ask right. so are 292's any good? they have a 3 angle valve job, decked to something, ported i think

i have no clue man, im just going with the info i got off of http://www.mortec.com well, except for how to find what kind of heads they were, friend showed me that. im pretty sure ive heard oval port heads is what you want. took me a while to find those, i was looking in the small block numbers :rolleyes:

sorry man, forgot to mention that they were off my 454, thats a cool site, i'm gonna use it alot now
